You decided to end the marriage. Steps have been taken as he has moved out. His trying to show up to plead to keep the marriage is probably done by everyone who doesn’t also want to end it. To have these conflicted feelings you have are also very ‘normal’.

If it turns into a back and forth where you take him back and throw him out over and over (I’m guilty of this), it is truly a toxic relationship. Yet, everything can improve with effort and understanding, if both work at it and want it to. It’s a personal decision. I’m not suggesting you stay or go. I hate to compare myself, it’s so hard not to do.
